Paper ancient times no matter how fast time to develop, how technological change, our life has become a paper record accompanied by many aides life, but in the papermaking process, a variety of raw materials due to the need to address the inevitably there are some small problems, foam It is one of them.
Paper defoamer more organic hydroxy compounds and fatty acid ethers, and synergists composed of lipids and other substances, has a strong defoaming function suds suppressors, demineralised hydrocarbons, environmentally friendly, and foaming medium good compatibility; stabilizing effect of storage period. Its efficacy can quickly eliminate paper coating cleanly produce large foam hazardous air knife blade when a force is applied through pumps, screens and coating process.
[Parameters Product
Appearance: colorless transparent liquid
component: fluorine-containing polyether and
water Solubility: soluble in water, excellent in dispersibility
ph: 5-8
Ion: non-ionic
[Features]
1, anti-foaming long fast suds suppressors, with less, not affect the basic properties of the product
2, good compatibility, high temperature alkali resistance, breaking does not drift, no delamination
3, without causing pinholes , spots and fish eyes, do not affect the appearance and quality of the coating
4, the coating does not cause a change in the consistency of the coated surface in both process quickly, cleanly remove fine bubbles
[Applications]
Paper defoamer for: sizing paper coating applicator, coating material, calendered printing paper magazines, wash deinking, paper coating polymer defoaming and deaeration systems, coated paper, pulp defoaming material, paper surface sizing pressing process, glues, defoaming coating process, the deinking process produces defoaming wet end use, paper production process defoaming degassing the like.
[Reference] The amount
added directly to the foaming system, need to uniformly stirred before use, recommended dosage: 0.1 to 0.8%, based on the actual amount of good final experiment.
